Clicks Soshanguve crossing bad service

Was in a que awaiting to be assisted, the manager suddenly clapped his hands towards me in a very rude manner telling me I'm next. Told him that there's no need for him to be so rude to his customers then he responded rudely in words I couldn't hear then I asked him to reiterate what he just said so that I can hear him but he just walked towards to the que. I felt disrespect as a loyal clicks client and I feel this will make it difficult for me to purchase anything from this specific store considering that should I encounter an issue in future I won't be able to communicate it with management which is him. Clicks at Soshanguve Crossing has disappointed me.
